Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to a deep cleaning system for conveyor belt return. Background Technology

[0002] Conveyor belts, also known as transport belts, are rubber and fiber / metal composite products, or plastic and fabric composite products, used to carry and transport materials. They are widely used in industries such as cement, coking, metallurgy, chemicals, and steel for short-distance and small-capacity conveying applications.

[0003] During the conveyor belt process, residues left by transported items will remain on the surface of the conveyor belt. These residues will contaminate the surface of the conveyor belt and cause wear and tear due to accumulation, thus accelerating the wear and tear of the conveyor belt. Therefore, a cleaning device is needed to clean the conveyor belt.

[0004] Traditional conveyor belt cleaning methods involve spraying the return working surface of the conveyor belt with water spray pipes installed at the unloading point at the head of the conveyor belt. This method is relatively simple and results in poor cleaning effectiveness.

[0005] In view of this, there is an urgent need for a deep cleaning system for conveyor belt return. Summary of the Invention

[0006] To address the problems existing in the prior art, the present invention solves this problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A conveyor belt return deep cleaning system includes: a frame, on which a head roller, a high-pressure flushing pipe, a scraper mechanism, an air knife mechanism, and a fan mechanism are mounted; the fan mechanism is used to supply high-pressure hot air to the air knife mechanism. The high-pressure flushing pipe is connected to the water supply pipeline. One end of the conveyor belt is wrapped around the head roller. The high-pressure flushing pipe, scraper mechanism and air knife mechanism are arranged in sequence below the conveyor belt from one side of the head roller. The high-pressure flushing pipe is used to flush the conveyor belt, the scraper mechanism is used to clean the conveyor belt, and the air knife mechanism is used to deliver high-pressure hot air to one side of the conveyor belt.

[0009] A water collection tray is also installed on the frame, located below the head roller, high-pressure flushing pipe, scraper mechanism, and air knife mechanism.

[0010] The frame is equipped with a housing, and the head roller and high-pressure flushing pipe are located inside the housing.

[0011] The frame is equipped with a floating frame and several elastic components. The side of the floating frame closest to the head roller is rotatably connected to the frame. Several elastic components are set on the frame, and the side of the floating frame away from the head roller is set above the several elastic components. The scraper mechanism is mounted on a floating frame.

[0012] The scraper mechanism includes several parallel mounting rods, which are mounted on a floating frame. The mounting rods are arranged sequentially from one side of the high-pressure flushing pipe toward one side of the air knife mechanism. Each mounting rod is equipped with several scrapers, which are arranged sequentially along the axial direction of the mounting rod.

[0013] The fan mechanism includes an outer casing, a motor, a scroll compressor casing, an air duct, and a first air pipe. The motor and the scroll compressor casing are located inside the outer casing. The outer sides of the motor and the scroll compressor casing and the inner side of the outer casing form an air chamber. A natural air inlet is provided on the outer casing, and the air inlet of the motor is connected to the natural air inlet. The vortex compression shell is provided with a C-shaped compression chamber. The vortex compression shell is provided with a compression inlet and a compression outlet, both of which are connected to the compression chamber. The motor's air outlet is connected to the air chamber, the air duct's air inlet is connected to the air chamber, the air duct's air outlet is connected to the compressor inlet, and the first air duct's air inlet is connected to the compressor outlet. The air outlet of the first air duct is connected to the air inlet of the air knife mechanism.

[0014] The compression inlet and compression outlet are located at opposite ends of the compression chamber.

[0015] The fan mechanism also includes a flow divider, which is located between the motor and the vortex compressor housing. The air outlet of the motor is connected to the inner cavity of the flow divider. The flow divider is circumferentially provided with several flow dividers that are connected to the inner cavity of the flow divider, and several flow dividers are connected to the air chamber. The air inlet of the air duct is located on the side of the vortex compressor shell away from the distributor.

[0016] The vortex compressor housing is annular, and the motor, vortex compressor housing, and flow divider are coaxially arranged.

[0017] The air duct includes an air guide plate and a second air duct. The air guide plate is located on the side of the vortex compressor shell away from the splitter cylinder. An air guide cavity is provided inside the air guide plate. The air guide cavity is connected to the air chamber through the air inlet of the air guide plate. The air guide cavity is connected to the second air duct through the air outlet of the air guide plate. The air outlet of the second air duct is connected to the compressor inlet.

[0018] The following beneficial effects can be achieved by using the structure described above in this invention: The conveyor belt return path is rinsed with a high-pressure flushing pipe, then the residual water stains on the return path surface are cleaned by a sweeper mechanism, and finally the moisture on the conveyor belt surface is removed by an air knife mechanism, thus ensuring that the cleaned conveyor belt surface is dry and will not affect subsequent material transportation; multiple cleaning methods work together to achieve the best cleaning effect. The floating frame, positioned on the side away from the head roller above several elastic elements, provides self-adaptability to the scraper mechanism. This allows the scraper to adapt to the undulations of the conveyor belt return surface as the scraper contacts it from bottom to top (the end of the floating frame near the elastic elements can bounce up and down, causing the scraper mechanism to move up and down). This ensures that the scraper adheres to the conveyor belt return surface while avoiding hard contact between the scraper and the conveyor belt return surface, thus reducing damage to the conveyor belt.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product or device.

[0023] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0024] Reference Appendix Figure 1-4 A conveyor belt return deep cleaning system is shown, comprising: a frame (such as...) Figure 1 As shown in Figure A), the frame is equipped with a head roller 1, a high-pressure flushing pipe 2, a scraper mechanism 3, an air knife mechanism 4, and a fan mechanism 6; the fan mechanism 6 is used to supply high-pressure hot air to the air knife mechanism 4. High-pressure flushing pipe 2 is connected to the water supply pipeline, and the conveyor belt (such as...) Figure 1 One end of the conveyor belt (as shown in Figure C) is wound around the head roller 1. The high-pressure flushing pipe 2, scraper mechanism 3, and air knife mechanism 4 are arranged horizontally below the conveyor belt from one side of the head roller 1. Several pressure rollers (such as...) are also installed on the frame. Figure 1 As shown in Figure B), the return surface of the conveyor belt is placed below several pressure rollers, and the return surface of the conveyor belt is limited by the pressure rollers. High-pressure flushing pipe 2 is used to flush the conveyor belt, scraper mechanism 3 is used to clean the conveyor belt, and air knife mechanism 4 is used to deliver high-pressure hot air to one side of the conveyor belt. Based on the above structure, the return path of the conveyor belt is rinsed by a high-pressure rinsing pipe 2 (which is equipped with several nozzles facing the conveyor belt to form a water jet). Then, the residual water stains on the return path surface of the conveyor belt are cleaned by a sweeper mechanism 3. Finally, the moisture on the surface of the conveyor belt is removed by an air knife mechanism 4, thereby ensuring that the surface of the cleaned conveyor belt is dry and will not affect subsequent material transportation. Multiple cleaning methods work together to achieve better cleaning results.

[0025] like Figure 1As shown, a water collection tray 5 is also installed on the frame. The water collection tray 5 is located below the head roller 1, the high-pressure flushing pipe 2, the scraper mechanism 3, and the air knife mechanism 4. That is to say, the wastewater from cleaning the conveyor belt is collected on the water collection tray 5 and then transported to the wastewater collection tank. The wastewater after cleaning is collected and sent to the wastewater collection tank. The wastewater from the wastewater collection tank is purified by the purification host. Then the purified wastewater is stored in the buffer tank and finally supplied to the high-pressure flushing pipe 2 for reuse. This realizes the recycling of water, protects the environment, and saves water resources.

[0026] like Figure 1 As shown, a housing 7 is installed on the frame, and the head roller 1 and the high-pressure flushing pipe 2 are both located inside the housing 7. The advantage of this design is that when cleaning the return surface of the conveyor belt, the sewage will not splash into the outside environment. After being isolated by the housing 7, the sewage flows back to the water collection tray 5.

[0027] like Figure 2 and Figure 3 As shown, a floating frame 8 and several elastic elements 9 are provided on the frame. The side of the floating frame 8 near the head roller 1 is rotatably connected to the frame. Several elastic elements 9 are provided on the frame. The side of the floating frame 8 away from the head roller 1 is provided above the elastic elements 9. The elastic elements 9 can be elastic balls or air bladders. The scraper mechanism 3 is provided on the floating frame 8. The advantage of this design is that it can provide the scraper mechanism 3 with self-adaptive capability. When the scraper 32 of the scraper mechanism 3 contacts the return surface of the conveyor belt from bottom to top, it can adapt to the undulation of the return surface of the conveyor belt (the end of the floating frame 8 near the elastic element 9 can jump up and down to make the scraper mechanism 3 move up and down). This ensures that the scraper 32 is in contact with the return surface of the conveyor belt while avoiding hard contact between the scraper 32 and the return surface of the conveyor belt, thus reducing damage to the conveyor belt.

[0028] Among them, such as Figure 3 As shown, the scraper mechanism 3 includes several parallel mounting rods 31, which are mounted on the floating frame 8. The mounting rods 31 are arranged sequentially from one side of the high-pressure flushing pipe 2 to the other side of the air knife mechanism 4. Each mounting rod 31 is equipped with several scrapers 32, which are arranged sequentially along the axial direction of the mounting rod 31. The scrapers 32 on each mounting rod 31 are arranged in a straight line to clean the return surface of the conveyor belt. The scraper mechanism 3 cleans the return surface of the conveyor belt multiple times to ensure the cleaning effect. Both ends of the mounting rods 31 are set on the floating frame through elastic structures. That is to say, both ends of the mounting rods 31 can float in the vertical direction relative to the floating frame 8, further improving the adaptability of the scrapers 32. In this embodiment, the elastic element 9 can be an air bladder, and the elastic structure can be composed of springs, so that the dynamic following performance of the scrapers 32 is better.

[0029] like Figures 4-7As shown, to achieve rapid air drying of the conveyor belt, the fan mechanism 6 includes an outer casing 61, a motor 62, a vortex compression shell 63, an air duct, and a first air pipe 64. The motor 62 and the vortex compression shell 63 are located inside the outer casing 61. The outer sides of the motor 62 and the vortex compression shell 63 and the inner side of the outer casing 61 form an air chamber 612. A natural air inlet 611 is provided on the outer casing 61, and the air inlet of the motor 62 is connected to the natural air inlet 611. A C-shaped compression chamber 631 is provided inside the vortex compression shell 63 (the C-shaped compression chamber 631 guides and compresses the airflow: after the gas enters the compression chamber 631, the airflow movement is obstructed, the speed decreases, and part of the kinetic energy is converted into pressure energy, thus achieving compression). A compression inlet 632 and a compression outlet 633 are provided on the vortex compression shell 63, and both the compression inlet 632 and the compression outlet 633 are connected to the compression chamber 631 (in this embodiment, the compression inlet 632 and the compression outlet 633 are connected to the compression chamber 631). The positions of 633 are preferably respectively set at both ends of the compression chamber 631); the air outlet of the motor 62 is connected to the air chamber 612, the air inlet of the air duct is connected to the air chamber 612, the air outlet of the air duct is connected to the compression inlet 632, the air inlet of the first air duct 64 is connected to the compression outlet 633; ​​the air outlet of the first air duct 64 is connected to the air inlet of the air knife mechanism 4. In this way, when the motor 62 does work, natural wind enters the motor 62 from the natural wind inlet 611, takes away the heat generated by the motor 62, and then is discharged into the air chamber 612, and then enters the air duct, and enters the compression chamber 631 through the air duct. The high-pressure hot air after being compressed in the compression chamber 631 is transported to the air inlet of the air knife mechanism 4 through the first air duct 64, and comes out through the air outlet of the air knife mechanism 4, and blows towards the conveyor belt at a certain tangential angle, thereby taking away the water vapor on the return surface of the conveyor belt; the air is rapidly pressurized by the fan mechanism 6 to release heat, forming a high-speed airflow with temperature.

[0030] like Figures 5-7 As shown, the fan mechanism 6 also includes a diverter cylinder 65, which is disposed between the motor 62 and the vortex compressor housing 63. The air outlet of the motor 62 communicates with the inner cavity of the diverter cylinder 65. The diverter cylinder 65 is circumferentially provided with several diverter ports 651 that communicate with the inner cavity of the diverter cylinder 65, and these diverter ports 651 communicate with the air chamber 612. The air inlet of the air duct is located on the side of the vortex compressor housing 63 away from the diverter cylinder 65. The advantage of this design is that the air discharged from the motor 62... Guided by the splitter 65, the hot air is discharged from the splitter port 651 on the ring side. Since the vortex compressor shell 63 is located between the air inlet of the air duct and the splitter 65, the hot air discharged from the splitter port 651 passes over the vortex compressor shell 63 and enters the air duct. Due to the influence of the hot air in the motor 62 and the compression chamber 631, the temperature of the vortex compressor shell 63 is relatively high. Therefore, when the hot air passes over the outside of the vortex compressor shell 63, the temperature rises further before entering the air duct.

[0031] In a further optimization, the vortex compressor housing 63 in this embodiment is annular, wherein the motor 62, the vortex compressor housing 63 and the diverter 65 are coaxially arranged to balance the air pressure on the annular side of the vortex compressor housing 63.

[0032] like Figures 5-7 As shown, the air duct includes a guide plate 66 and a second air duct 67. The guide plate 66 is located on the side of the vortex compressor shell 63 away from the splitter cylinder 65. A guide cavity is provided inside the guide plate 66. The guide cavity is connected to the air chamber 612 through the air inlet of the guide plate 66. The guide cavity is connected to the second air duct 67 through the air outlet of the guide plate 66 via a pipe. The air outlet of the second air duct 67 is connected to the compression inlet 632. In this way, the hot air passing through the circumferential side of the vortex compressor shell 63 enters the guide plate 66, then enters the second air duct 67, and finally enters the compression chamber 631 for compression.

[0033] The air inlet of the air guide plate 66 is located on the side of the air guide plate 66 close to the vortex compressor shell 63; and the air inlet of the air guide plate 66 is composed of several air inlet holes 661, so that the hot air discharged from the diversion port 651 passes over the circumferential side of the vortex compressor shell 63 and finally enters the air guide cavity through the air inlet holes 661.

[0034] In this embodiment, the first air duct 64 and the second air duct 67 are preferably arranged side by side.

[0035] like Figure 4 As shown, in this embodiment, the outer casing 61 is provided with a filter screen at the natural air inlet 612 to prevent foreign objects from entering the motor 61.

[0036] like Figure 4 As shown, in this embodiment, the bottom of the outer casing 61 is provided with several support feet 68. The support feet 68 are made of elastic material, so that they have the function of shock absorption and energy absorption.

[0037] Further optimizations include a differential pressure return port (to release excess pressure; when the fan operation causes excessive internal system pressure, the differential pressure return port can return some airflow to the air inlet or low-pressure area to avoid equipment overload) and a pressure balance air supply port (to introduce fresh external air to maintain the pressure balance of the outer casing 61) to ensure the normal operation of the fan mechanism 6.

[0038] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that are directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
